I have nothing against ultra-efficient hybrids either. But electrics don't need a whole new infrastructure - not for autos with a 250 mile range. You would charge them at home, at night with off peak power (homeowners could put in plugs in their parking spaces; apartment owners would be required to do the same for tenants - one hell of a lot cheaper than the infrastructure for a hydrogen transition.) And electric cars are extremely zippy - great acceleration. Also don't forget plugin-hybrids. Take your muscle hyber-hybrid, and add a charger. Now you can travel the first 40 miles on the stored electricty (which is more than a lot of people travel in a day) and use fuel only for daily mileage exceeding that.
Mind you, a hell of a lot of auto travel is a matter of practicallity not auto love. Look at auto ownership rates in Manhattan - around 1/4th* or less the U.S. average**. Automobile ownership is less practical there than the U.S. average (parking + traffic) and mass transit better.
Provide really good mass transit nationwide - not merely manhattan level, but say better than Euro-travel (such as automated ultra-light rail) and a lot of people would gladly give up their cars. Because automobile love is so celebrated for commerical reasons, I think it is overlooked how many people in the U.S. drive who really don't like driving.
